フェライト熱電能特性 Thermoelectric Power of Ferrites
Measurements are reported of the thermo-e. m. f. of a thermoelectric junction composed of polycrystalline ferrites or double-layered ferite films as a function of the temperature. Thethermo-e. m. f. of the bulk and ferrite films was much larger than that of the conventional thermoelectric junction made of metals. A positive or negative thermoelectric power was observed depending on the difference in the combination of ferrites. Application of a magnetic field had a reducing effect upon the thereto-e. m. f. at temperature of room to the curie temperature. The temperature dependence was almost linear from room temperature up to about 500°C and above which it showed a tendency to saturate. This may perhaps be due to the structual peculiarites of the ferrites.
